I think the toolbar is a os-specific thing, as long as you speak of xp and below you can only have one mask color (no alphashading). The possibility you have is to draw the toolbar by yourself on the canvas - like ingame menus and so on.
Hm to you idea of precalculation: therefor you would have to read the colors set in the desktop-configuration (if no themes are enabled - because of missing solid color areas (textures, ramps...)) and then to precalculate the bordercolors.
With Linux in mind - i think they are capable of using alphachanelled icons.
